Description

回路基板によっては、1つではなく複数のプロセッサあるいは電子部品を冷却する必要がある。米国特許出願公開第2012/0132402号公報に開示されているように、2つのプロセッサに対して、二相ループを追加する代わりに、1つの二相ループにおいて、2つのエバポレータと2つのコンデンサを直列に配置することが提案されている。しかしながら、この解決策は、熱負荷が均一でない場合には適当なものではなく、さらに、始動に問題を生じ、このようなループの動作が不安定になる可能性があることがわかっている。米国特許出願公開第2002/0007937号公報に開示されているように、二相ループにおいて、複数のエバレータを並列に配置する解決策も提案されている。しかしながら、この構成では、それぞれのエバポレータは、ループ内における駆動効果を増加させることなく、ループ内における圧力損失を増加させてしまうため、その性能は限定的なものとなる。 Depending on the circuit board, it is necessary to cool a plurality of processors or electronic components instead of one. Instead of adding a two-phase loop to two processors, as disclosed in US 2012/0132402, two evaporators and two capacitors are connected in series in one two-phase loop. It has been proposed to be placed in. However, it has been found that this solution is not suitable when the heat load is not uniform, and further causes problems in starting and can make the operation of such a loop unstable. As disclosed in U.S. Patent Application Publication No. 2002/0007937, in the two-phase loop has also been proposed a solution to place a plurality of evaporator interpolator in parallel. However, in this configuration, each evaporator increases the pressure loss in the loop without increasing the driving effect in the loop, so that its performance is limited.
